determined it has a 10.5 to 1 cr with cast iron heads. He recommends to keep it the same and burn 30% racing fuel with 92 octane gas. That way I can keep the HP I currently have. I fugure I will only put on 500 miles in a year and this would be the best solution.

CR in the 10's/machine for quench($$$ though)/good ign curve/however much% racing fuel it needs. The desired/best SCR will be dependant somewhat on the cam choice
